WELL-DmLLlNc APPARATUS".

SPESEFICATION forming part of Letters Patent No. 306,792, dated October 2l, 1884.

Application filed July 0 all whom, it may concern:

Be it known that I, SIMEN WHEELAND, of Brownsville, in the county of Saline and State of Missouri, have invented certain'new and uscful Improvements in Well-Drilling Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention,whieh will enable others skilled in the art to which it appertains to make' and use the same, reference being had to the accompanying drawings, and to letters of' reference marked thereon, which form a part of this specification.

The object of' this improvement is an efficient well-drilling appliance. rlhe invention consists in the4 peculiar construction and arA rangement ofthe parts, as will be hereinafter fully explained and specifically claimed,refer ence being had to the drawings herewith filed as part hereof, in which the same letters of reference denote the saule parts in the different views.

Figure l is a perspective View of a well-drill embodying the features of my improvement. Fig. 2 is a sectional end elevation of the same. Fig. 3 is a perspective View of one of the parts detached. parts detached.

A A A2 represent a frame provided with lvertical extensions A3 c', and a circular openf ing fitting over a cylindrical vertical extension, B, of a base-frame, B B2, on which the frame A'A Al is arranged to revolve for a purpose hereinafter set forth.

C is a vertical beam, tenoned at its lower end to a transverse beam, C', having journals c, by means of which, with strapsG, it is flexibly connected to the vertical extension A.

C2 represents metal braces for additionally securing the connection of the vertical beam G to the transverse beam C, and a is a Z- shaped metal brace for securing the position of the parts to whiclritis connected, as shown.

D is a pulleyr secured to the upper part of the beam C by means of meta-l arbor D', to receive and act as a bearing for the rope D`-,con necting with the well-drill (not shown) and with an automatically adjustable link or frame, HL', by means of a clamp,lH, secured to the rope D, and to the link H2 by means of bolts if.

E is a shaft provided at its outer end with a double cam, H, for a purpose hereinafter set Fig. 4 is a top view ofone of the 17,1884. (No modeLl l forth, and with disks F F,which serve as guards for winding the rope D2, and elevating the drill from the well as occasion may require. The shaft E revolves in bearings c c, secured to vertical extensions af A:vz of the revolving frame A A A`.

El isa gear-wheel secured to the inner end of the shaft E, and arranged to meslrwith a pinion, G, secured to a shaft, G, having a wheel, A, rigidly affixed to its outer end, as shown, and arranged to revolve in a swivel metal bearing, G, secured to the frame A A2, near its outer end, and an adjustable metal bearing, K, affixed to the transverse beam a, and having a slotted extension, K, for a purpose hereinafter set forth.

H is a. metal frame or link, iiexibly connected to the lateral extension a c* of the revolving frame by a pivot-bolt, 71, and provided with a friction-roller, h. The vertical beam C has a metal addition, CL C5, having a pivot, C, for the reception of a perforated plate, M, having radial hooked projections M M2 M.

L L L`` are guy-ropes for steadying the machine.

K2 is a lever connecting by means of a link, 1., with the adjustable bearing K for the shaft G, forthe purpose of putting the 'pinion G on the shaft G out of gear with the pinion E on the shaft E, and in gear with the pinion or idle-gear Gi, for the purpose of thereby reversing the motion of the shaft E, and elevating the drill from the well by winding the rope D-y thereon, the latter being previously disengaged from the clamp Hi", and secured to the disk F by means of staple or hook affixed thereto, as shown at j.

The mechanism. is put in operation by one or more draft-animals connected through the usual single or double tree to the ring-bolt N, on the frame-extension A, and driven in a circuit around the vertical extension B of the base frame or platform B B2, which is to be rigidly secured inl position by any suitable means. As the frame A A AL' moves around through the gearing G E2 to the shaft E, provided at its outer end with the double cam H, which will pass through the link or frameflg, and periodically engage with friction-roller h, affixed to the link H, flexibly connected to YSo the platform-extension B, the wheel An1 will.

revolve and give motion to the shaft G, and

roo

the frame-extension d a, and by bearing the saine downward elevate the well-drill until the ends Hl of the earn H pass the roller 71', when the drill will drop with the usual effect. As ihe drilling progresses, ille rope D2 is lowered through the clamp H", as occasion may require. Then the work is done, the ilexiblyconnected vertical extension C is lowered on the part A A A for convenience ol" transporting, for which purpose the parts Il. H2 may he disengaged from the frame-work and i'roni each other.

Having explained the construction and op` eration of my improvement, what l elaini as new, and desire to secure by Letters Patent,
